A hypothesis that selenium deficiency predisposes the development of occupational cervicobrachial complaints was tested in 134 females working in an assembly factory, with constrained work postures and repetitive work tasks. Seventeen subjects, who reported intake of selenium tablets, had higher plasma selenium levels than the others (104 vs 89 micrograms/l, P = 0.01). Among those who did not take selenium tablets, 21% reported symptoms from the upper back during the last 7d, 21% from the neck, 38% from the shoulders, 15% from the elbows, and 27% from the hands. Subjects with pain in their elbows had slightly, but significantly, lower plasma selenium levels than asymptomatics (84 vs 90 micrograms/l, P = 0.048). For the other anatomical regions, there were no statistically significant differences. Thus, there was no major association between selenium status and pain; conclusions regarding any minor association must await further studies.
在一家装配工厂工作的134名女性中，对硒缺乏易导致职业性颈臂部不适这一假设进行了测试，她们的工作姿势受限且工作任务重复。17名报告服用硒片的受试者血浆硒水平高于其他人（104微克/升对89微克/升，P = 0.01）。在未服用硒片的人中，21%报告在过去7天内上背部有症状，21%颈部有症状，38%肩部有症状，15%肘部有症状，27%手部有症状。肘部疼痛的受试者血浆硒水平略低于无症状者，但差异显著（84微克/升对90微克/升，P = 0.048）。对于其他解剖区域，没有统计学上的显著差异。因此，硒状态与疼痛之间没有主要关联；关于任何微小关联的结论必须等待进一步研究。
